DIY All Glass Tank Build Question on Overflow/Sump
I've been out of the hobby for a few years (since 2010 when I deployed). At that time I was the proud owner of the rebuilt Big Clear Kahuna that I had picked up from Scolley and remade. When the deployment came around I simply couldn't expect my wife to watch our 4 kids and take care of the aquarium so I found a good home for it and haven't had an aquarium since. Rebuilding the Big Clear Kahuna was a good experience and I love the way a rimless low iron glass tank looked so I would like to build a new one.
With the previous tank I had a canister filter and i ran all of the equipment inline. It was a PVC engineering marvel but I would like to simplify and make some things (like auto top off, autodosing) easier to do and so I've decided to include an overflow/sump.
In line with the minimal stuff in the tank idea of the sump I would like to have a minimalist overflow as well. I'll be having the glass cut to order and want to have it set up correctly when I order it.
Here is what I am thinking please tell me where I am going wrong.
I would like to cut a weir into the back panel of glass that would extend about one half of the total length of the tank (total length will be 40 inches). It would be about half an inch lower, no teeth and would then go into an external overflow that would be set up with a bean animal type drain. This will allow the tank to be very near full and have nothing in the way as far as scaping and lighting. The external overflow would then be siliconed into place at the level of the top of the rest of the tank. This will allow the water level to be about 1/2 inch from the top of the tank and it will allow the overflow box to be as shallow (front to back) as possible. I've looked at add in boxes from glass holes and the ghost overflow but the Ghost one said the highest water level would be 1.75 inches from the top and I couldn't find anything on the threejole from Glass Holes.
What do you guys think? Any better options?
